Explanation:
Malise has 1 something (may be a pound, any unit) and she uses 1/8 to make pancakes and 1/3 to make a pie. To see what fraction of blueberries are left we have to substract 1/8 and 1/3 from 1:
[tex]1-\frac{1}{8}-\frac{1}{3}[/tex]We have to find the lower common denominator. Since 8has factors 2, 2, 2 and 3 has itself as a factor (and of course 1 for both) the LCD is the product of these two: 8 x 3 = 24.
Now we have to write it and in the numerator, we have to write each numerator multiplied by the quotient between the LCD and each denominator:
[tex]\frac{1\cdot\frac{24}{1}-1\cdot\frac{24}{8}-1\cdot\frac{24}{3}}{24}=\frac{24-3-8}{24}=\frac{13}{24}[/tex]Answer:
The fraction of blueberries left is 13/24
